Fifty million years ago, the Arctic hosted alligators and lush forests, but ever since, Earth's climate has cooled. Over the last few millions years, Earth's position relative to the Sun has driven the advance and disappearance of ice sheets over northern North American and Eurasia. This has shaped Georgia's landscapes and biodiversity. The burning of fossil fuels is performing a "carbon spike experiment" on the climate system, turning it toward warming. How could this effect Georgia?

Dr. Bill Witherspoon is Past President of Georgia Geological Society and co-author of Roadside Geology of Georgia, a popular guide to the science behind Georgia's favorite natural destinations. Having retired in 2014 after 17 years of teaching at Fernbank Science Center, he is now studying climate science and climate economics at Georgia Tech.
